This can be tested with a "noid" light probe for each injector harness connector. The fuel pressure reading should be around 51 psi which would be a static reading. If the engine is unable to start, turn the ignition key to the run position but DO NOT TRY TO START THE ENGINE. You should see fuel going into the can at a good rate for several seconds.

If the bulb is burnt out, the charging system will not charge.Īt this point you'll have to determine if there's an ignition or fuel delivery problem:Īn easy way to test the fuel pump and filter is to disconnect the fuel feed hose from the fuel rail and connect it to a long length of spare hose with the other end draped over the fender going into a catch can placed on the ground. If a vehicle is not charging properly and the battery is good, the first thing to do is to turn the ignition switch to the "ON" position without starting the engine and make sure the charging system warning light is operating. If a battery is not good, the charging system may not be able to charge properly. A battery should have a static charge of 12.2-12.6 volts.

When a charging system is not charging, or overcharging, a lot of "strange" things can occur like idling funny or stalling, unable to start or anything out of the "norm," test the charging system before you start pulling hairs!Ī properly working charging system puts out about 13.2 to 15.0 volts.
